Title: Elctronic cash register
Inventor: IMAI YASUSHI
IPC: G06Q50/00
Filed: 1980-08-07
Abstract: PURPOSE:To prevent various kinds of data totalized by a normal work from being destroyed by preparing the first and the second memory devices corresponding to a normal work and a training work respectively. CONSTITUTION:With the first mode change-over switch 6 having a state changed to a normal work, a CPU10 performs a normal work by judging that the switch 6 has been a state of a normal work and substituted number data have been inputted. In such a state, since an FFT15 is in a reset state, the first AM12 is in an active state and the second RAM13 is in an inactive state. On the other hand, a training work, when the switch 6 is switched to a training work, after the CPU10 judging that the switch 6 is switched to a training work, outputs a training start signal TS. Hereby, the FF15 is set and the RAM12 is made to be nonoperated thus allowing the PAM13 to be made active.
